Hillary Clinton would like to see a woman U.S. president

WASHINGTON (Reuters) - Hillary Clinton has fed speculation that she might run for the White House in 2016 by telling an audience in Canada that she would like to see a woman president in the United States in her lifetime.

"Let me say this, hypothetically speaking, I really do hope that we have a woman president in my lifetime," Clinton told a private audience in Toronto. "And whether it's next time or the next time after that, it really depends on women stepping up and subjecting themselves to the political process, which is very difficult."

Clinton, a Democrat who was secretary of state under President Barack Obama, a former senator from New York and is the wife of former President Bill Clinton, is said to be undecided whether to seek the presidency in 2016.

Many Democrats and Republicans in the United States are expecting her to run, although the 65-year-old Clinton has said she needed to rest after four years as a globe-trotting secretary of state.

Polls have indicated she is far and away the most popular potential Democratic candidate for 2016, and that most Americans would prefer her to several possible Republican contenders.

Clinton picked up an endorsement on Tuesday from Missouri Senator Claire McCaskill, who announced she is supporting a group encouraging Clinton to run for the White House.

McCaskill, who backed Obama over Clinton in the Democratic primaries in 2008, became the first member of Congress to announce her support for Clinton.

She praised the political action committee called Ready for Hillary for using the Internet to build support in the hope that Clinton will run.

Last week Clinton started her official Twitter account, describing herself as, among other things, a "wife, mom, lawyer, women & kids advocate." She alluded to her future as "TBD" - to be determined.

In her speech in Toronto, delivered on Thursday and posted on YouTube on Friday, Clinton said electing a woman president would "would send exactly the right historic signal to girls, women as well as boys and men. And I will certainly vote for the right woman to be president."
